説明

Farom was launched in Japan for use as an antibiotic against common respiratory tract pathogens. It can be prepared by several related routes of about seven steps starting with tetrahydrofuran-2-thiocarboxylic acid and a silylated azetidinone. It is a broad spectrum oral penem antibiotic that is β-lactamase stable. Farom is the most active β-lactam against anaerobes (more than cefaclor, cefixime and amoxicillin) but also has activity against Gram-positive, Gram-negative and enterobacteriaceae. It is equally active against strains carrying plasmid and chromosome mediated β-lactamases. The short plasma elimination half-life is the result of hydrolysis by renal dehydropeptidase. It is more stable to hydrolysis by extended spectrum β-lactamases than some second and third generation cephalosporins.
